The person has to learn what they can handle, get the most information, and make their own informed decision.
And at what point do others have the right to an informed decision. e.g.
the federal/state gov't (which pays for much of medical training) and
the medical school (which rejects someone in favor of you) and
THE PATIENTS?
Do you tell each patient during clinical yrs that "I'm a medical student, and you deserve to know that I've been diagnosed with a psychotic disorder known as schizophrenia - but my doctor and I believe it is currently under good control?"
And after you become a physician, will you be telling each and every patient you meet?
If not, why not? Do they really have no right to this information right up front?
Would you support such a person becoming a police patrol officer with a gun without notifying the academy or the prospective employer?
Anybody want to be on the first transatlantic flight with my hypothetical pilot whose sight may be getting worse as we speak, but (s)he might not know it yet - and the stress of a 10+ hour flight might exacerbate it?
Schizophrenia is a condition that may be stable, possibly even remitted. But if it worsens, the physician affected may not realize the impact on judgement, concentration, thought process until after it is too late.
This is not like a painful condition wherein the affected physician can make a definitive decision ahead of time like, "I will not see patients when I'm on opiates."
This is really not the same as an addicted professional who is either using or sober, for which there is a definitive test that you could (conceivably) administer each day before work.
A professor in med school laid out a pretty basic way to determine whether you should fear that something (involved in your medical practice) is unethical or might be affecting your judgement: If you think your patients would find it disturbing to know, and you're avoiding letting them find out - you probably should not be doing it.
So let me ask again: Will you tell all your patients up front?
I'm really sorry, but this is
not just about you and fulfilling your dream.
